Isopropanol is prepared through catalytic hydrogenation of acetone by feeding hydrogen gas and acetone liquid into a reactor having a fixed catalyst bed from its top to form a concurrent gas/liquid downflow while maintaining the catalyst bed in a trickle bed state. This process can produce isopropanol at a high reaction rate in high yields using a simple reactor.

Isopropanol obtenu par l'hydrogénation catalytique d'acétone en intégrant, à partir du haut, de l'hydrogène et de l'acétone dans un réacteur à support de catalyseur fixe, pour obtenir un courant descendant concurrent de gaz/liquide tout en maintenant le support de catalyseur en position d'écoulement en mince filet. Ce procédé permet d'obtenir de l'isopropanol à une vitesse de réaction élevée et en grande quantité, à l'aide d'un simple réacteur.
